The Rational Unified Process (RUP) is a software engineering process developed and marketed by Rational Software Corporation. The RUP comprises a host of software development best practices collected from a number of contributors, over many yeras, and across a wide variety of situations. The RUP is popular because it provides a disciplined approach to assigning and managing tasks and responsibiltites to ensure success in a software project. In this new book, the industry’s leading RUP experts borrow from their significant experience and insider knowledge to teach you how to apply the RUP and succeed with it. The reader will discover what works, and what doesn’t, as well as specific advice on how and when to apply the RUP. Overall, the reader will gain knowledge of how the RUP impacts their job, and how this process can benefit their organization.

This is more or less the last thing I did with Rational Software before its acquisition by IBM, and my departure.

The original RUP book, still going strong, actually. A much decried piece by many agilistas, who consider this as the typical example of what not to do (but then, they usually have not read the book!). Available in 11 languages (see some pointers below).
